2025 ICD-10-CM code A17.89
(Active) Effective Date: N/A Tuberculosis - Other tuberculosis of nervous system Certain infectious and parasitic diseases (A00-B99) Feed
Other tuberculosis of the nervous system.This includes tuberculous polyneuropathy.
Medical necessity is established by the presence of signs and symptoms of TB affecting the nervous system, confirmed by appropriate diagnostic tests. The documentation must support the diagnosis and justify the chosen treatment approach.
Clinicians diagnose this condition based on lab tests, medical history, and imaging studies (MRI or CT). They manage the condition with antituberculous chemotherapy, sometimes combined with steroids, and may perform surgery if necessary.
In simple words: This code refers to tuberculosis (TB) that affects the nerves outside the brain and spinal cord.It's a rare but serious form of TB.
This code identifies tuberculosis (TB) affecting the nervous system excluding the brain, spinal cord, and meninges. It encompasses conditions like tuberculous polyneuropathy (damage to multiple nerves or nerve groups). Symptoms include paresthesia, hypoesthesia, fever, headache, focal neurological deficits, behavioral changes, paresis, numbness, and altered mental status. Diagnosis involves testing specimens for Mycobacterium tuberculosis, tuberculin skin tests, and evaluating medical history. Treatment includes antituberculous chemotherapy (isoniazid, rifampin, rifabutin, pyrazinamide, and ethambutol), potentially with adjunctive steroid therapy.Severe cases may require surgical removal of tuberculomas.
Example 1: A patient presents with numbness and tingling in their extremities, along with a history of TB.Diagnostic tests confirm M. tuberculosis in the peripheral nervous system, leading to a diagnosis of tuberculous polyneuropathy (A17.89)., A patient undergoing treatment for TB develops new-onset weakness and sensory loss.After excluding other causes, the physician diagnoses other tuberculosis of the nervous system (A17.89)., A patient with a past history of TB presents with fever, headache, and focal neurological deficits not attributable to CNS involvement.Further investigation reveals TB affecting the peripheral nervous system, coded as A17.89.
Documentation should include evidence of TB infection (e.g., positive culture, skin test), neurological findings (e.g., sensory loss, weakness), and imaging results if applicable. The specific site of nervous system involvement should be clearly documented.
